Why German wonder weapons could not reverse the war

Could any German wonder weapon have changed the outcome of the Second World War?

Not realistically; even a vastly more destructive V-2 would still be too late, too inaccurate, and vulnerable to the loss of its launch territory.

The panel finds no German wonder weapon able to reverse the historical outcome on its own. A V-2 with a nuclear warhead is the only theoretical exception raised, but even that requires range and accuracy far beyond the operational weapon. By the time the missile entered service, Germany was retreating rapidly and Allied ground forces could overrun its launch areas. A weapon aimed mainly at Britain could inflict terror and damage without stopping the armies already dismantling the system that fired it.
